(57) A firewall penetration system is provided for use between a firewall (102) and a
penetrating member (104). The system comprises a first annular plate (114) with an
outer and an inner radial wall (120,122) and an axial wall (124) coupled therebetween,
the axial wall (124) extending axially away from the outer radial wall (120), and
the inner radial wall (122) extending radially inwardly from the axial wall (124)
and having an opening (134) through which the penetrating member (104) may extend.
The second annular plate (116) has an outer section (138), an inner section (140),
an inner peripheral edge (143) defining an opening (144), the outer section (138)
configured to couple to the first annular plate outer radial wall (120), the inner
section (140) configured to define a seal cavity (146) with the first annular plate
axial wall (124) and inner radial wall when the annular plates (114,116) are coupled
together. The compressible seal (118) is configured to be disposed in the seal cavity
(146), and has a bulb (148) and a leg (150) extending therefrom.
